citizen of the United States, residing at f Bakersfield, in the county of. Kern and the following is a specification.

My invention relates generally to sweep-. ing appliances and more particularly to. brooms or brushes having relatively long heavy bristles and "which are utilized for sweeping pavements, concrete floors and the like; the principal objects of my invention being to generally improve upon and simpllfy theconstruction of the 'existing types of. similar'brooms or brushes, and toprovlde a relatively .simple and practical broom; or brush structure 'that is capable of being easily and cheaply. produce Further objects of my invention are, to I provide a broom or brush having a handle that is reversible sothat it may be readily] shifted from one side of the brush body to the other, thereby enabling the brush tobe, used so that the wear upon the bristles 1s substantially uniform, and. further, to provide, simple andreadlly detachable means that will permit the tufts orbunches of bristles to be readily removed from the brush. back in the eventthat thebristles become.- und'uly worn, thereby enabling the brush to be renewed from time to time by thelin replace those that sertion of new bristles to have been worn away,

H With the foregoing and. other objects in view, my invention consists in: certain novel features of construction and arrangementv of partsthat will be'hereinafter more fully described and claimed.- and illustrated. in

the accompanying: drawings, in which:

whichmay be formed'of woodgcompressed fibre, hard rubber, or analogous material,

and formed in the underside of said body disposed rows. The members of eachlongitudinally disposed row of recesses are connected by short longitudinally disposed. slots 12, and arrangedatthe centerof the brush body and intersecting the longitudinally disposed slots 12,.is a transversely=dis posed slot 13. i

Removably positioned zononeendof the brush body andheld thereupon by nieans'of screwsilc is a'plate15, preferably ofmetal, in which is formed a seriesof apertures 16, the same being arrangedjso that they'coincide with the adjacent ends-of the longi tudinally disposed grooves- -or slots 12.

Removably positioned on the opposite end of the brush body. and retainedvthereupon by screws 17 ,:'-isa' metal plate, 17 in;which isformed aseries,of ;notches 18 that extend upwardly from the lower edge ofsaidplate and said notches being arranged so that they coincide with the adjacent ends of thelongitudinally disposed grooves orslots 12. i V 1 Fortions vof the lower edge of plate 17 ad acent toits ends are bent inwardly to form narrow lips or flanges 19 which, when theplate is properly applied to the end Fig.7. isan end elevational view of a modlfiedform of the brush andwith a portion ofthe handle thereof in section.

ing drawings; which illustrate. a, practical embodnnent ot mypinventlon, 1O 'deslgnates of the brush'body, overlie the under surend portion 'ofsaid body. (See arran'gedin bunches that are, doubled at their centers, and a series of the bunches thus doubled is arranged on a retalmngmember 21, preferably a wire or narrow .,strip of metal. that 1s sl ghtly longer than the brush body 10, and one 01 these bristle carrying members is arranged in each longitudinally disposed slot or groove 12 with the doubled central portions of the bristles carried by said member positioned within the corresponding recesses 11; and, to retain the brush carrying members 21 in position in the brush back, said members, at one end, are bent hooks 22 that engage through the apertures 16 in plate 15.

The opposite ends of the bristle carrry ing members 21 project through the upper portions of the notches-18 in" plate 17 and said ends are supported in proper position at the upper ends 01 said notches, by a transversely disposed strip 23, preferably otmetal, that is-positioned beneath plate 17 and clamping against the adjacent end of the brush back when the end plate retaining screws 17 are tightened.

Overlying the central portion of the brush back 10 is a transversely disposed plate 24:, the ends 01 which extend downwardly over the front and rear faces of said brush back, said plate being secured to the brush back in any suitable manner by means of screws 25, and, formed in. the depending end portions of this plate, are apertures 26 that coincide with the ends of the transverse groove 13.

Extending through the transverse groove 13 and arranged beneath the bristle carrying members 21, is a transversely disposed supporting member 27, preferably, a wire or a narrow metal plate, the end portions of which are bent to form depending hooks 28 that engage in the apertures 26, such construction providing a substantial support for the intermediate portions of the bristle carrying'members 21.

Fixed to and projecting upwardly from plate 24 is a vertically disposed plate 29, and pivot-ally connected thereto by means of a transversely disposed pin or boltESP. are the lower ends of the arms of a yoke 31, which latter is provided with a threaded shank 32 that is seated in the lower end of a handle 33.

Seated in the upper portions of the arms of the yoke 31 are set screws 34 that are adapted to bear against the side faces of plate 29 to lock the handle carrying yoke 31in its angularly adjusted. position.

virtue of the construction just described, it ispossible, when one side of the body of bristles of the brush have become worn oflf as a result of continued use, to release the set screws 3% and swing the handle 33 from an angular position on one side of the brush body to, a corresponding angular position on the other side; and, by so doing, the wear upon the ends of the bristles of the brush may be evenly distributed. When, after continued use, the bristles become worn so as to lee-unfit for service, the bristle downwardly to formcarrying members 21 may be readily detached from the plates 15 and 17, thereby enabling the old and worn bristles to be re moved and replaced by new bristles.

To effect a removal of the bristle carrying members 21, it is only necessary to loosen screws 17 a a sufficient degree to permit plate 17 tobe swung outward a suflicient distance to'release the transverse retaining strip 23, after whichthc adjacent ends of the retaining members 21 may be pulled downwardly from their positions within slots 12 in the brush back.

Inthe modifiedconstruction illustrated in Fig. 7 the upper edge of the transverse plate 29 is provided with a series of notches 35 and, inwhich is adapted to engage the lower end of a spring pressed pin 36 which latter is arranged in asuitably'located recess in the;

handle carrying yoke 31*. By retracting pin 36 the handle carried by the yoke maybe swung into various angular positions with respect to the brush body and locked in such adjustedposition by the engagement of the i ner end of said pin inone of the, notches 85.'

A brush of my improved construction is comparatively simple, may be easily and cheaply produced, is constructed so that old or worn bristles mayv be readily removed and.

replaced new bristles, and the brush handie is arranged so that it may be readily shifted from one side of the brush body to the other, thereby bringing about an even distribution of the wear upon the outer ends of the bristles.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved broom or brush may be made and substituted for 'those herein shown and described without those ends of the retaining members extend ing through said openings, a plate secured to the back intermediate its ends, and retaining strips within the transverse slot and extending through the intermediate plate and, the lipped plate and between the lipped plate and said back, and cooperating with said hooks for securing the retaining members within the slots.

2. A brush comprisin a back having bristle receiving recesses ancslots formed ther in connecting the recesses, plates secured to the ends of the back and at a point medially thereof, bristle retaining members Within said slot, and extending through the end 5 plates, hooks formed on one end of the retaining members for securing the same to one end plate, and retaining strips associated with the other plate and engageable with the retaining members for securing the latter Within said slots.

In testimony whereof I have name to this specification.
